Answer:
A severe depletion of ozone in a region of the ozone layer, particularly over Antarctica and over the Arctic. The depletion is caused by the destruction of ozone by CFCs and by other compounds, such as carbon tetrachloride (CCl4) and carbon tetrafluoride (CF4).

Chemical leavening agents are baking soda and a mixture of baking powder. It reacts immediately when added to liquids because it causes two separate reaction to occur in the dough. The first reaction happens when the baking powder is mixed with liquids; it causes carbon dioxide to be produced. The second reaction occurs when the heat mixed during the baking process; causes further expansions.
Use the formula E=hv, h=plancks constant and v=frequency
use the formula c=v*lambda to find v
the answer will be 2.88*10^-23J
